2006 jetta tdi radio not working after jump start

Car wouldn't start yesterday...had to be jumped. Radio was working...and now it's not. No power at all. It's not in Safe mode and the radio card number can't be entered since the radio will not turn on. Any ideas? Fuses look ok under hood.

The battery was jumped, then I had it replaced with a new one. Car runs fine. The radio just won't come on now.The battery was jumped, then I had it replaced with a new one. Car runs fine. The radio just won't come on now.

I jumped started my 2004 jetta and now my radio des not work. I checked the fuse (#42) on the panel but its ok. could it be the fuse on the back of the radio? what's the possibility of that?I jumped started my 2004 jetta and now my radio des not work.

Radio and lights on radio do not work. The number 20 fuse is good.Radio and lights on radio do not work. The number 20 fuse is good.

you may have blown a fuse... check the fuse in the interior fuse panel under the dash. if your car has a cigarette lighter check to see if it works as it 's usually on the same fuseyou may have blown a fuse... check the fuse in the interior fuse panel under the dash. if your car has a cigarette lighter check to see if it works as it 's usually on the same fuse

Did you find a solution to this problem? I have the same issue, fuses are fine, dealer says the radio is fried but they didn't even try to connect it to another car. It's hard for me to believe the radio is dead when both fuese are fine.

To unlock your VW factory radio from "SAFE" mode, you will need to enter the radio code. Typically, the code is written on a radio card included with the documentation for the vehicle when the car is first sold.

If you don't have the code, or have lost it, you can retrieve it by visiting your VW dealer. You will need the car's VIN number and the serial number of the radio (located on the body of the radio).

The procedure to enter the code is as follows:

Press the "MODE" and "SCAN" buttons simultaneously and hold
them until "1000" appears on the radio display. Release the buttons as
soon as this number appears.

Refer to your Radio Card and use the station preset buttons ("1",
"2", "3" and "4") to input the code. Press the "1" button repeatedly to input the
first digit, the "2" button to input the second digit, etc.

Press and hold the "MODE" and "SCAN" buttons simultaneously until "SAFE" appears again. Release, and the radio should be unlocked.

Do not enter the wrong code more than three times, or the radio will lock itself. Note the dealer can also enter the code for you (they may charge a small fee).

It sounds like you probably have a shorted battery cell. This will not only cause the repeated clicking that you described, but it will also rob power when jump-starting from another vehicle. There is probably enough power when jump starting to turn the starter over, but after the starter take the power that it needs, there is not enough power to operate the computer system....so I have no doubt that you probably are not getting any fuel. The computer has to tell the fuel pump to run. If there is no power for the computer....I think you can figure it out from here.

probably a fuse, unless its an aftermarket radio that lost complete memory mode, and need to be re coded to work. the easiest way to check this is to look for the power wire, on your car its a blue wire with a yellow stripe for the battery one, and a gray wire for the ignition one that supply the radio with 12 volts, see if they have power,

The radio goes in safe mode when the battery gets disconnected, or if for some reason the radio lost power connection.

To get the radio out of safe mode you will need the anti theft code.
This is available with car documentation, in first page of the in car entertainment booklet, or on first page of the car booklet (not the car manual).

Once you have got the code, do the following:

Hold down both the AM/FM and the SCAN button at the same time, until the display shows "1000".

Use the buttons 1,2,3,4 to change each of the digits until you get displayed the same code as printed on documentation (ensure that it is the right one).

On some radio (programmable models), the default code is "1111" or "1234".

Press and hold the AM/FM and SCAN buttons again until the radio is starting.

If you fail twice the code, the radio will lock up in safe mode, and you won't be able to enter the code again.

If the radio is locked, or if the code is lost, the unlock can be done at the nearest car dealer, usually for a small fee, or for free.

Hi
Wiih most radio units....If you have the proper code and have NOT tried
more than 15 times to enter an incorrect code....you should be ok.
Turn OFF ignition switch and remove the key. Switch OFF interior lights. Switch ON Radio unit and SAFE will appear.
Leave everything alone for a period of ONE HOUR. During this time
NO power (no matter how small) should be drawn from the battery.
This is why the interior lights MUST NOT come ON when the door is
opened. Trunk should also remain closed. In the event of any power been
drawn from the battery in this time...You must start all over again.
Radio should after this time return to standard mode...Usually 4
flashing bars. Then enter your code. Dont forget to lock in the code
and all should be fine
All the best with it

Make sure you have the radio code found inside your model information packet inside your glovebox…it will be on the radio and communications pamphlet. It is in safe-mode right now, so press and hold the FM button and the scan button until 1000, or whatever number is stored in your safe mode, appears. Enter your code by selecting the pre-set radio station buttons until the corresponding number appears; press and hold the FM button and scan button again and your radio should be reset.
